Notes:
 
During the libjava test the natgetlocalvartable.cc compilation was OK but  
the next few lines are:
 
JVMTI getlocalvartable Interpreted Test
WARNING: program timed  out.
FAIL: getlocalvartable run
UNTESTED: getlocalvartable output
 

The program was compiled using:
 
/opt/gcc-4_3-build-2/gcc/xgcc -B/opt/gcc-4_3-build-2/gcc/  
/root/downloads/gcc-4_3-trunk/libjava/testsuite/libjava.jvmti/interp/natgetlocalvartable.cc  \
-shared -fPIC -I. -I..

-L/opt/gcc-4_3-build-2/i686-pc-linux-gnu/./libstdc++-v3/src/.libs -lstdc++   
-lm   -o libnatgetlocalvartable.so
 

I am able to "execute" ".so" files on my OS - they print version info.  If I 
try to run libnatgetlocalvartable.so I get this:
 
# ./i686-pc-linux-gnu/libjava/testsuite/libnatgetlocalvartable.so  
Segmentation fault
 
It happens immediately. The expect scripts for this part of the libjava  test 
are not correct - since they exist before the complete set of 
files is  available and attempt to run the shared library instead of some 
future SVN  included file that would link to this ".so" .
 

If I try this instead (just an added "-Ii686-pc-linux-gnu/libjava" and  
removed the ".so" to make a '".exe"') I get the same result:
 
cd /opt/gcc-4_3-build-2

-lm   -o libnatgetlocalvartable
 
# ./libnatgetlocalvartable 
Segmentation fault
 

Upon examination of natgetlocalvartable.cc I can conclude that it is a  
portion of some larger set of code. This file (natgetlocalvartable.cc) 
and  the test for this file where committed to the SVN directory _without_ 
any  supporting files.
 

-----
 
The failures in the libstdc++-v3 tests executions are due to my deleting  all 
references to "-lm" from the configure and 
Makefile (in accordance with  
_http://gcc.gnu.org/gcc-4.3/changes.html#mpfropts_ (http://gcc.gnu.org/gcc-4.3/changes.html#mpfropts)   ). I left these 
reports (and the spike they 
cause) in since the configure  script / Makefile / testsuite combination is 
poor (in my opinion) but it exposes  a collect2 fault. Here is why I have such 
thoughts ;) (don't mind the "CFLAGS",  they work).

"ceilf" in "libstdc++.so.6" then why does it link with "-lm" ?).

# ./2.exe
(Prints nothing)
 
When I substituted "-lm" with "/usr/lib/libm.a" it linked and ran without  
printing anything. I imagine that this is a "correct" result.
 

I also tried to substitute  
"i686-pc-linux-gnu/libstdc++-v3/libmath/.libs/stubs.o" and  "i686-pc-linux-gnu/libstdc++-v3/libmath/.libs/stubs.o"
but both gave a  "Segmentation fault" when ran; though they linked OK. Oddly, 
using  "i686-pc-linux-gnu/libstdc++-v3/libmath/stubs.o"
produced a file that  compiled without error and ran. This program 'froze' 
and hitting CTRL-C (or Z)  was needed to terminate it (it printed no errors).
 
 
 
I tried again but added a "-v" to see what was happening:
 

gcc/g++ -v ...

(prints nothing)
 

Since both collect2 commands are the same, except the second specifies  a 
path for the first "libm", it leads one to wonder where collect2 thinks it  will 
find the second "libm" (it won't).
 
The reason this error is hidden is because libstdc++.so.6 and other parts  of 
libstdc++-v3 are linked with libm - the one used in collect2 (shown above) is 
 ignored.
